Title: Wafer positioning device
Inventor: IIDA EIICHI
IPC: H01L21/68
Filed: 1985-10-23
Abstract: PURPOSE:To execute a positioning of the linear change-over part while the positioning accuracy of the center of a discal wafer is maintained by a method wherein the wafer is rotated while being held reliably by a large frictional force, is rotated by changing-over to smaller frictional force and is positioned on the reference position. CONSTITUTION:When an electric signal is outputted to a check electromagnetic valve circuit, a wafer 2 is attracted and held on a chuck part 31. A rotating chuck body 29 is made to ascend while holding the wafer 2, stopped at the position indicated by two-dot chain lines and rotated counterclockwise. By this rotation, when a flat 5 approaches the position to roughly superpose on the reference line, a detecting circuit detects this and the detected signal is sent out to the chuck electromagnetic valve circuit and so on. After a drive control circuit is stopped, the relation between the chuck part 31 and a depressurizing source is severed, an attracting action to the wafer 2 is stopped and the wafer 2 continues rotating by a frictional force due under its own weight. Subsequently, the flat 5 is pressed to the reference face by the force of a very small pressing spring 85 and the wafer is positioned.

Abstract: PURPOSE:To recognize an object at a high speed by extracting the feature points of each of binary images obtained by >=3 units of 2-dimensional image pickup means, securing the correspondence between the feature points and calculating the 3-dimensional coordinates of the corresponding point on the subject. CONSTITUTION:Feature points PA, PB and PC of a point P on an object appear on images HA, HB and HC obtained through TV cameras 1A, 1B and 1C respectively. An image epipolar line l2 of a straight line connecting the focal point of the camera 1A and said feature points is set on the 2nd image HB. The feature point PB of the image HB is set on the line l2, and the feature point PC of the 3rd image HC is set on an intersecting point of epipolar lines l3 and m3. Thus it is understood that the feature points PA-PC are opposite to each other as images at the point P. Therefore the 3-dimensional coordinates of the point P are obtained in the form of an intersecting point among straight lines FAPA, FBPB and FCPC.

Title: Buffer device with re-transmission function
Inventor: KAWACHI YOSHIKAZU
IPC: G06F13/40
Filed: 1992-09-04
Abstract: PURPOSE:To improve the efficiency at the re-transmission in which a transfer efficiency is largely reduced in a buffer of data transfer. CONSTITUTION:Data are inputted to a buffer b1 from a sender side terminal equipment, and when a write attribute bit w1 is logical 0, logical 1 is written to the bit, data are stored in a data buffer d1, logical 1 is set to a write pointer 102, a succeeding buffer is advanced and the processing is repeated for a required number of times. Upon the receipt of a reception enable signal 90 from a receiver side terminal equipment, data represented by a pointer 103 are outputted and the read pointer 103 is advanced to a next pointer. When any line error is in existence, a restart signal 60 is received, data are sent again and when the transmission is finished, a transmission finish data abort signal 50 is received, a write attribute bit wn is reset and data from a position pointed out by the read pointer 103 till its head are erased. Thus, after the data are sent once, the re-transmission is attained for many number of times by having only to revise the control signal.

Title: Production of photothermomagnetic recording film
Inventor: KATAYAMA SHINYA
IPC: C01G49/00
Filed: 1985-10-23
Abstract: PURPOSE:To obtain a photothermomagnetic recording film which is decreased in surface defects, has high adhesive power and excels in magnetic characteristics and magnetooptic characteristic by sputtering the surface of a substrate with an ionized or activated gas then forming a film consisting of the components for forming Bi-substd. rare earth iron garnet. CONSTITUTION:After the surface of the glass substrate is sputtered by the ionized or activated gas, the film of the components for forming the Bi-substd. rare earth iron garnet is formed on the surface thereof by a sputtering method. The sputtering of the glass substrate surface is executed by impressing the high frequency of 0.1-5.0W/cm<2> to an atmosphere of Ar, O2, N2, etc., kept under 1X10<-3>-1X10<-1>Torr to generate high-frequency plasma and accelerating the gas ions of the ionized Ar, O2, N2, etc., to bombard the ions onto the substrate surface. The layers of the contaminants such as oxides and carbides which stick to the surface of the substrate and cannot be removed by an ordinary cleaning operation are thereby removed and the surface is roughened, by which the constituting atoms of the substrate and the constituting atoms of the oxide film are more easily bound with each other. The adhesive power is thus increased and the generation of exfoliation or cracking is made difficult.

Title: Detection of dust clogging
Inventor: NAKAMURA YUJI
IPC: G01N1/22
Filed: 1987-09-21
Abstract: PURPOSE:To enable detection of the condition of dust clogging a gas sampler pipeline which samples a coarse gas containing dust to be introduced to an analyzer, by determining a pressure value in a sample gas pressure charged piping. CONSTITUTION:A gas containing dust such as a gas 1 in a blast furnace is sampled and the gas sampled is introduced to a gas analyzer 7 through a dust removing filter 5 and a sample gas pressure charged piping 6 to detect the condition of dust clogging a gas sampler. In other words a pressure in the sample gas pressure charged piping 6 after the start of charging a pressure rises gradually and finally, equals the pressure such as that in the blast furnace to complete the charging of the pressure. A pressure ascension curve obtained here varies depending on the dust clogging condition of the pipeline from a gas sampling point to the pressure charged piping 6. The pressure rising speed decreases as the clogging with dust progresses, which inevitably prolongs the time to complete the charging of pressure. Thus, conversely, the dust clogging condition of the pipeline in the upstream side can be detected by checking a shift of pressure in the pressure charged piping after the start of charging pressure with a pressure sensor 9.
